Question

Which expression converts 4pi radians to degrees?

Answer 1

Answer:

$4\pi$ radian = 720 °

Step-by-step explanation:

Given  : 4pi radians .

To find : Which expression converts 4pi radians to degrees.

Solution : We have given that 4pi radians .

1 radian  = $\frac{\pi }{180}$.

$4\pi$ radian = $\frac{\pi }{180}$.

$4\pi$ radian = $4\* 180$  *  $\frac{\180 }{180}$.

$4\pi$ radian = 4 * 180

$4\pi$ radian = 720 °

Therefore, $4\pi$ radian = 720 °

Answer 2

4pi/2pi = x/360
use a proportion
2 radians equals 360 degrees
x = 720 degrees
